Application filed December 7, 1914. SeriaI'No. 875,817.

To all whom it may concern:

Be it known that I, ALBERT CASPER, a citizen of the United States, residing at Vallejo, of California, have invented certa1n new and useful Improvements in Vehicle- Chocks; and I do declare the following to be a full, clear, and exact description of the inv tion, such as will enable others skilled in t e art to which it appertains to make and use the same.

This invention relates to improvements in foldable chocks for vehicles.

The object of the invention is to provide a vehicle chock which is so constructed that it may be quickly opened and applied and readily removed and collapsed into a small space after use to provide for its convenient transportation on the vehicle with which it is to be used.

Another object is to provide a device of this character which will reliably fit the tire of the Wheel to which it is to be applied and securely engage the supporting surface of the vehicle to hold it against turning in they direction in which this chock is placed, thereby rendering it especially useful for checking a vehicle on an upgrade when it is desired to stop for any purpose.

Another object is to provide means for detaching the chock and drawing it into the vehicle without necessitating the driver leaving his seat.

With the above and other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts as will be more fully described and claimed.

In the accompanying drawings, Figure 1 is a side elevation of this improved chock applied; Fig. 2 is a horizontal section thereof taken on the line 22 of Fig. 1; Fig. 3 is a transverse section taken on the line 3-3 of Fig. 2; Fig. 4 is a transverse section taken substantially on line 4-4 of Fig. 1 showing the pivotal connection of the braces with the shoe; Fig. 5 is a side elevation of the chock in folded collapsed position; Fig. 6 is a plan view thereof.

In the embodiment illustrated, two wheel engaging shoes 1 and 2 are shown connected by two links 3 and 4 which are pivotally engaged with said shoes. These shoes are also provided with adjustable supporting means to be described. The shoes 1 and 2 have transversely curved wheel receiving seats in the county of Solano and State.

constructed to conform to the curvature of the tire of the wheel to which they are to be applied and of a Width corresponding to the width of the tire. As shown, these shoes are constructed of sheet metal although they may be formed of any other suitable material and each of them is provided with a pair of lugs 5 and 6 which project from their opposed edges at one end thereof and are here shown folded downwardly and riveted at their terminals to the shoes to provide bearings for the links 3 and 4, the ends of which are disposed between the folded portions of the lugs and pivotally connected therewith the shoes relatively to the links. The surface engaging shoe 1 is provided on its outer face at the tread rality of surface engaging spurs 7 which are designed to engage the supporting surface of the vehicle and assist in holding the chock n operative position.

Connected to the shoe 2 on opposite sides of the outer face thereof are two supporting braces 8 and 9 which are connected at one end with said shoe, by universal joints 10. These braces 8 and 9 are provided at their free ends with surface engaging spikes 11 which are designed to penetrate the surface on which the vehicle is supported to assist in holding it in chocked position. braces 8 and 9 are adjustably connected by any suitable means, a chain 12 being here shown connected at one end with one of the braces near its spiked terminal and a hook 13 is provided on the other brace at a point' opposite the chain of brace 8 and which is designed to be engaged with one of the links of said chain for adjustably connecting said braces to vary the distance between them. These braces 8 and 9 are adapted to be detachably and adjustably connected with the surface engaging shoe by any suitable means, two chains 14 being here shown connected with the rear end of said shoe 1 at opposite sides thereof and they may be of any suitable or desired length, being connected with the braces by passing the spiked ends 11 thereof through one of thelinks in the chains and by means of this connection, the pitch of the spiked braces may be varied to suit the height at which it is desired to support the wheel engaging shoe 2.

The lugs 5 and 6 of the surface engaging shoe 1 are disposed at the front end of the shoe While those of the shoe 2 are disposed portion thereof, with a plu-.

These to provide for the adjustment of at the rear end thereof to adapt the links 3 and 4 to provide protective means for the edges of the shoes when in folded or collapsed position.

A flexible element 15 is secured to the rear end of the shoe 2, preferabl at the tread thereof and is of a length su cient to permit the free end thereof to be held by any suitable means at the front of the vehicle so that it may be grasped by the driver to draw the chock into the vehicle after the vehicle has beenstarted, which will release the chock and permit it to be easily pulled forward. v

In the operation of this improvedphock, the shoes 1 and 2 are opened and the surface engaging shoe positioned at the rear of the vehicle wheel to which it is to be attached as shown in Fig. 1, and the braces 8 and 9 are then adjusted to bring the shoe into engagement with the wheel at a point above that which is engaged by the shoe 1. When in this position, the links 3 and 4 are disposed on opposite sides of the wheel tire and the device is secured in operative position by causing the spiked ends 11 of the braces to be inserted in the surface on which the vehicle is mounted, the chains 14 having first been properly positioned for the passage of these spiked ends'through the desired link thereof. It is to be understood that the spread between the braces is preferably adjusted before the braces are passed through the connecting chains 14 but the chain 12 may be adjusted to take up any slack therein such as might occur when the braces are positioned closer'together than the length of the chain or the distance be-- tween the link which is connected with the hook 13 of the other brace. The universal joints 1O permit these braces to be disposed at any desired angle and they are usually? disposed with their engaging spikes placed in planes beyond the planes of the sides of the shoe 1, thereby aflording a rigid supportfor the vehicle to which the chock is applied. While one of these chocks has been described, it is obvious that two of them are preferably employed for chocking the two rear wheels of the vehicle or if found necessary, all four of the wheels may be so chocked. The chocks themselves, being comparatively small, will occupy very little space in the vehicle when transporting them and are ready for use when desired. After a chock has been drawn into the vehicle, the shoes 1 and 2 are folded inwardly against the links 3 and 4 and the braces 8 and 9 are folded inwardly adjacent said shoes. The chains 12 and 14 are then folded into the shoes and the. chock is ready to be placed out of the way in any suitable space.

I claim as. my invention a plurality of Wheel engaging shoes, means connecting said shoes to locate them at different positions on the periphery of a wheel,

surface engaging means carried by one of said shoes, and combined surface engaging and supporting means connected with the of a wheel, surface engaging means carried by one of said'shoes, and combined surface engaging and supporting means connected with the other, and means for detachably and adjustably connecting said supporting means with said first mentioned shoe. 4.
